Low to high fan speed control - US design
USX series are electronic fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 6 A. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology. The output voltage towards the motor can be manually regulated via the central knob from minimum to maximum. This knob also has an OFF position. The minimum speed can be adjusted via an internal trimmer. The enclosure is designed for surface mounting.
